Stainless Steel Protection Tube
Protection tube is used for thermocouple or thermal resistance. It is designed to protect the temperature sensor from flow, high pressure and harsh environments.
It is matched with thermocouple(thermal resistance)and bimetallic thermometer to ensure their normal operation. It is also used for environment under high pressure or with high flow speed.
Nominal Pressure
It generally refers to sustainable static pressure from outside on protection tube without breakage. It concerns not only material, diameter, wall thickness of protection tube, but structure and mounting way of the tube, flow speed and category of tested media as well.
Water Pressure Test
It is conducted to checking pressure resistance and leakage of protection tube. Testing pressure shall be 1.5 times of pressure-proof class of protection tube.
